7. Are all the voltages within specifications ? I If the voltage drops are correct, go to Step 8, to check the engine. I If the voltage drops are too high, repair and/or replace the faulty electrical component. Start Relay Tests D167422 Relay 1. Put the multimeter on the 200 ohm scale. 2. Put the multimeter lead to the 85 and 86 terminals. 8. Rotate the crankshaft by hand to make sure it is not locked up. Check oil viscosity and any external loads that would affect engine rotation. 3. The indication on the meter must be 82 L 5 ohms. If the indication is not correct, the start relay must be replaced. 9. Is the engine locked up or hard to turn ? I If it is, repair the engine as required.
I If the engine is not hard to turn, go to Step 10. 4. Put the multimeter leads to the 30 and 87 terminals. 5. The indication must be "OL"(Over Load). If the indication is not correct, the start relay must be replaced. 10. Does the starting motor crank? I If it does crank, remove the starting motor for repair and/or replacement. I If it does not crank, check for blocked engagement of the pinion and flywheel ring gear. 6. Connect WH wire to 86 and BK wire to 85 terminal with the ignition switch to start position. Put the meter lead to 30 and 87 terminal. 7. The indication must be Zero ohm. If the indication is not correct the start relay must be replaced. NOTE:
Blocked engagement and open solenoid contacts will give the same electrical symptoms. G424 Service Manual Starting System 35
